SL-1237型高分辨率电阻率测井仪器的研制

The Development of High - resolution Deep-investigation Resistivity Tool——SL-1237

高分辨率电阻率测井仪器采用自由式控制的供电方式,综合了侧向测井仪器和微电阻率测井仪器的特点,仪器的垂直 分辨率为50 mm,探测深度为330～500 mm。仪器能够准确探测薄层的真电阻率,准确划分油层的厚度,有效地克服泥浆、 井眼对测量结果的影响,识别渗透层和裂缝发育地层。介绍了仪器的设计方案、技术指标及应用效果。

High-resolution deep-investigation resistivity tool is controlled by freely switchable power supply mode which integrates the properties of laterolog tool and micro-resistivty tool with a vertical resolution of 50 mm and an investigation depth of 300-500 mm. It can measure the true resistivity of thin-bed, determine the thickness of beds,eliminate the effects of mud and borehole and identify permeable and fracture-developed formation, so the tool is an important tool to enhance the production in the later developing period of oil field. This paper introduces the design and technical properties of the tool and its application effects.
